Hi, this is a question for writing package definition. In some scenarios package A may refer to source files in package B. The question is, 1. How to reference source directory of package B from within definition of package A? 2. can we even assume sources of Package B is available? Normally if package B is an input (dependency) for package A, guix would ensure its installation directory is available, but not necessarily the source. So is there something that has to be done to ensure Package B sources are somewhere?
Thanks for info on these.
